2. The voice coil is bonded to the vibrating diaphragm to form a vibrating system, the vibrating system is large in mass, and the sound pressure output is low.

3. The voice coil loudspeaker voice coil is with the mode that the vibrating diaphragm was glued, and the frequency response curve low frequency band appears the peak valley and breaks easily, is unfavorable for the high-fidelity output of sound.

4. The voice coil loudspeaker voice coil vibrates along with the vibrating diaphragm, and the vibrating diaphragm amplitude is not of uniform size, leads to the voice coil loudspeaker voice coil lead wire rupture easily, influences the life of speaker.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a simple structure, sound pressure output height, tone quality high-fidelity output, long service life's novel speaker to the not enough of prior art existence.

In order to achieve the above object, the utility model discloses a technical scheme of speaker is:

the utility model provides a novel loudspeaker, which comprises a bracket, the support is provided with the convex cover, and the inboard bottom of convex cover bonds and has the voice coil loudspeaker voice coil, leaves the clearance between voice coil loudspeaker voice coil outer wall and the convex cover inner wall, and the voice coil loudspeaker voice coil stretches out there are two lead wires, and the pin connection has the rigid coupling in the wiring board of support, and the voice coil loudspeaker voice coil outside is provided with the vibrating diaphragm with the support rigid coupling, leaves the clearance between vibrating diaphragm terminal surface and the voice coil loudspeaker voice coil terminal surface. The voice coil is connected with alternating current audio current to generate a magnetic field, and under the action of ampere force, the magnetic diaphragm vibrates to compress air to generate sound with the same waveform as the original audio signal.

Preferably, the support is provided with a plurality of tuning through holes, and the tuning through holes are covered with tuning nets. The tuning net improves acoustic performance.

Preferably, the tuning through holes are arranged in an arc shape. The tuning net can be made into corresponding arc-shaped sheets, so that the assembly is convenient.

Preferably, the support is provided with an inner frame for accommodating the diaphragm. The vibrating diaphragm is bonded to the inner frame of the support.

Preferably, the terminal block includes a base plate provided with two terminal plates. The two terminal boards are respectively connected with the voice coil lead and a wire for inputting alternating current audio current.

Compared with the prior art, the utility model, have following advantage:

1. the vibrating diaphragm is made of a magnetic material, and the magnetic circuit system and the vibrating system are combined, so that the structure is simplified, the assembly process is less, the production efficiency is high, and the production cost is reduced;

2. the voice coil is directly bonded with the bracket, so that the mass of the vibration system is greatly reduced, and the output sound pressure is improved;

3. the voice coil is separated from the diaphragm, so that the low-frequency section of a frequency response curve is prevented from being broken by peaks and valleys, and high-fidelity output of sound is facilitated;

4. the voice coil loudspeaker voice coil does not vibrate along with the vibrating diaphragm, avoids the voice coil loudspeaker voice coil lead wire because of the vibrating diaphragm amplitude is not of uniform size, leads to the phenomenon of rupture easily to improve the life of speaker.

fig. 2 is an exploded view of fig. 1.

The voice-frequency tuning device comprises a support 1, a convex cover 11, an inner frame 12, a tuning through hole 13, a voice coil 2, a lead wire 21, a wiring board 3, a bottom plate 31, a terminal board 32, a vibrating diaphragm 4 and a tuning net 5.

Detailed Description

The present invention will be further clarified by the following description in conjunction with the accompanying drawings, which are to be understood as illustrative only and not as limiting the scope of the invention, and modifications of the various equivalent forms of the invention by those skilled in the art after reading the present invention are within the scope defined by the appended claims.

As shown in fig. 1-2, the voice coil tuning device comprises a support 1, a convex cover 11 is arranged on the support, a voice coil 2 is bonded at the bottom of the inner side of the convex cover, a gap is reserved between the outer wall of the voice coil and the inner wall of the convex cover, the voice coil extends out of two leads 21 which are connected with a wiring board 3, the wiring board is an arc plate, the wiring board is arranged at one side of the convex cover and is coaxial with the convex cover, wires are convenient to weld, the wiring board comprises a bottom plate 31, two terminal boards 32 are arranged on the bottom plate, the two terminal boards are respectively connected with the leads of the voice coil and the wires for inputting alternating current, a vibrating diaphragm 4 is arranged at the outer side of the voice coil, a gap is reserved between the end face of the vibrating diaphragm and the end face of the voice coil, the vibrating diaphragm is made of a magnetic material, an inner frame 12, for improving acoustic performance.

The utility model discloses a concrete working process and principle:

the voice coil is connected with alternating current audio current through the wiring board to generate a magnetic field, and under the action of ampere force, the magnetic diaphragm vibrates to compress air to generate sound with the same waveform as the original audio signal. The utility model combines the magnetic circuit system and the vibration system, simplifies the structure of the loudspeaker, reduces the assembly process, improves the production efficiency and reduces the production cost; simultaneously with voice coil loudspeaker voice coil and vibrating diaphragm separately, reduce vibration system's quality, improve output sound pressure, avoid appearing frequency response curve low frequency section peak valley and play a discount, do benefit to the high fidelity output of sound, also avoided the voice coil loudspeaker voice coil to vibrate along with the vibrating diaphragm, lead to the phenomenon of voice coil loudspeaker voice coil lead wire rupture easily to improve the life of speaker.
